Intel is one of the world's largest chipmakers. It designs and manufactures microprocessors for the global personal computer and data center markets. Intel pioneered the x86 architecture for microprocessors. It is also the prime proponent of Moore's law for advances in semiconductor manufacturing. While Intel's server processor business has benefited from the shift to the cloud, the firm has also been expanding into new adjacencies as the personal computer market has declined. These include areas such as the Internet of Things, memory, artificial intelligence, and automotive. Intel has been active on the merger and acquisitions front, recently acquiring Altera, Mobileye, Nervana, and Movidius in order to assist its efforts in non-PC arenas.
